Abstract
Undercarriage down lock director, including fixing round pin axle and two bolts on lock shell inner wall, two bolt settings that are located the locking arm top are in the both sides of round pin axle, and all are equipped with the direction piece between locking arm and two bolts, be equipped with the torsional spring on the screw rod of bolt, a reed of this torsional spring lies in between direction piece and the bolt, and another reed lies in between bolt and the round pin axle, one side that the direction piece deviates from the locking arm is equipped with stop pin, its characterized in that: the stop pin periphery sets up the swivel becket, and the lower part of swivel becket sets up curved blotter, and the upper portion of direction piece sets up soft lug, lug and blotter cooperation. Direct contact no longer between direction piece and the round pin axle at first contacts through lug and blotter, and rotate the syncline top under the effect of buffering mat lug, squints the orientation of direct impact power a little, becomes flexible collision, has effectively reduced the rigidity and has collided the loss that leads to the fact. The locking arm after -separating, the blotter is got back to and is resetd bottom under the action of gravity.
Description
Technical field
The utility model belongs to aircraft mechanical field, specifically a kind of undercarriage down lock guides.
Background technology
Publication number CN202368788U discloses a kind of undercarriage down lock guide piece, and this device is resilient engagement, effectively reduces to collide when hammerlock 7 coordinates with lock housing 6 to cause loss.But find in practice that between guide piece and bearing pin, collision frequency is more, guide piece damages comparatively serious, and replacement frequency is higher.
Utility model content
The utility model provides a kind of undercarriage down lock guides, in order to solve defect of the prior art.
The utility model is achieved by the following technical programs:
Undercarriage down lock guides, comprise and be fixed on bearing pin on lock-shell lining and two bolts, two bolts be positioned at above hammerlock are arranged on the both sides of bearing pin, and guide piece is equipped with between hammerlock and two bolts, the screw rod of described bolt is equipped with torsion spring, a reed of this torsion spring is between guide piece and bolt, another reed is between bolt and bearing pin, the side that described guide piece deviates from hammerlock is provided with stop pin, it is characterized in that: stop pin periphery arranges swivel becket, the bottom of swivel becket arranges the cushion rubber of arc, the top of guide piece arranges soft projection, projection coordinates with cushion rubber.
Undercarriage down lock guides as described above, another reed of described torsion spring is sleeved in cutting ferrule, and two cutting ferrules are linked by spring leaf.
The utility model has the advantages that: in the utility model, no longer directly contact between guide piece with bearing pin, first contacted with cushion rubber by projection, rotate obliquely upward under the effect of cushion mat projection, the direction of direct impact power is offset a little, become flexible impact, effectively reduce the loss that rigid collision causes.After hammerlock is separated, cushion rubber is got back to and is resetted bottom under gravity.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model; Fig. 2 is the I partial enlargement structural representation of Fig. 1; Fig. 3 is that Fig. 1 obtains II partial enlargement structural representation.
Figure number marks: 1 guide piece, 2 torsion springs, 3 bolts, 4 bearing pins, 5 untie-sells, 6 lock housings, 7 hammerlocks, 8 swivel beckets, 9 cushion rubbers, 10 projections, 11 cutting ferrules, 12 spring leafs.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Undercarriage down lock guides, as shown in the figure, comprise and be fixed on bearing pin 4 on lock housing 6 inwall and two bolts 3, two bolts 3 be positioned at above hammerlock 7 are arranged on the both sides of bearing pin 4, and guide piece 1 is equipped with between hammerlock 7 and two bolts 3, the screw rod of described bolt 3 is equipped with torsion spring 2, a reed of this torsion spring 2 is between guide piece 1 and bolt 3, another reed is between bolt 3 and bearing pin 4, the side that described guide piece 1 deviates from hammerlock 7 is provided with stop pin 5, stop pin 5 periphery arranges swivel becket 8, the bottom of swivel becket 8 arranges the cushion rubber 9 of arc, the top of guide piece 1 arranges soft projection 10, projection 10 coordinates with cushion rubber 9.In the utility model, no longer directly contact between guide piece 1 with bearing pin 4, first contacted with cushion rubber 9 by projection 10, rotate obliquely upward under the effect of cushion rubber 9 projection 10, the direction of direct impact power is offset a little, become flexible impact, effectively reduce the loss that rigid collision causes.After hammerlock 7 is separated, cushion rubber 9 is got back to and is resetted bottom under gravity.
Specifically, in order to prevent the reed of torsion spring 2 and bearing pin 4 from departing from, another reed of the torsion spring 2 described in the present embodiment is sleeved in cutting ferrule 11, two cutting ferrules 11 are linked by spring leaf 12.Spring leaf 12 by two torsion spring 2 locking positions by cutting ferrule 11, can be kept the reed of torsion spring 2 certain limit to swing simultaneously again, have natural active.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
